vlc crashes encoding MP3

[Thomas]

I started a screen recording (see commandline) and then I opened a other movie with nautilus. Because I set VLC to single instance mode, the recording crashed.

[Rémi Denis-Courmont (rdenis)]

We do not accept Debian bugs on the "VLC media player", sorry.

[Rémi Denis-Courmont (rdenis)]

I am not able to reproduce the problem with either VLC 1.1.13 or 2.0.0. Also the specified command line does not include any audio track, so it is probably not correct.

Please specify how to reproduce the bug, otherwise we cannot do anything.
